 ### Highlights [elasticsearch-900-highlights]
 
 ::::{dropdown} rank_vectors field type is now available for late-interaction ranking
-
 [`rank_vectors`](../reference/elasticsearch/mapping-reference/rank-vectors.md) is a new field type released as an experimental feature in Elasticsearch 9.0. It is designed to be used with dense vectors and allows for late-interaction second order ranking.
 
 Late-interaction models are powerful rerankers. While their size and overall cost doesn’t lend itself for HNSW indexing, utilizing them as second order reranking can provide excellent boosts in relevance. The new `rank_vectors` mapping allows for rescoring over new and novel multi-vector late-interaction models like ColBERT or ColPali.
